Abstract (en)
[origin: US4726717A] A deep-bore drilling machine consists of a deep-bore drilling unit (1) which is driven by rotation and has a deep drill tool (4, 7). The front end (7) of the deep-bore drilling tool (4) is led into the drill bushing (10) at the beginning of the drilling operation. The drill bushing (10) is thereby contained in a main spindle (22) and is replaceable. Also, the main spindle (22) can also be driven independent of drive (2) of the deep-bore drilling unit (1) by another drive (30).
